I just did. First Red Alert 3, which works fine, and then Kane's Wrath.

Edit: I tried CnC 3 right after, same error as in KW.

I have looked at this in the log. You are actually authenticating and then there is a system error. Please could you try logging in with a different OnlineID (just make up a new one, and if that is in use, try a different one) and report back.

I never get the chance to log in. The game freezes when I hit Online menu and after a really long time gives the Cannot connect error: 

I've never been able to login before either afaik.

PS: Sorry for the big ass picture.

PPS: Red Alert 3 seems to work just fine.

I've already added Kane's Wrath as exception to the (advanced) firewall; I checked (with a internet traffic tool) the connection of KW and there is some traffic inbound and outbound.

In-game under Settings/Network, my own internal IP address is shown as Online IP; I cannot select or see any other IP address there.
